I added the spot mirrors, but found after packing a large H2W's bag I could not see behind me as well...
Adding the K mirrors took some visual getting used to, but they seem to be a stock look to me now.
Part of the problem for me may be that I always ride with the large topcase installed.....only time I have had it removed since I bought the bike is to take it in for service. Not sure how my vision would be without it. But I'm getting used to them too.......and liking what I see. (pun intended)
